[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 In this embodiment, a refrigerator filter element capable of removing odors includes a coconut shell activated carbon rod 1. The upper side of the coconut shell activated carbon rod 1 is provided with an upper outer shell 2, and the outer side of the coconut shell activated carbon rod 1 is provided with a lower outer shell 3. The upper and lower ends of the coconut shell activated carbon rod 1 are respectively equipped with a carbon rod upper cover 4 and a carbon rod lower cover 5. A water channel plate 6 is provided on the upper side of the lower outer shell 3, and a handle 8 is provided on one side of the upper outer shell 2.

[0024] The upper outer shell 2 has a cross-sectional shape resembling an eye mask. The inner side of the upper outer shell 2 has four regularly distributed circular pillars. The back of the upper outer shell 2 has an arc-shaped step whose size matches the size of the handle 8. A crescent-shaped notch is provided above the arc-shaped step.

[0025] It should be noted that the coconut shell activated carbon rod 1 is a filter element made from high-quality coconut shell activated carbon. The carbon rod filter element is made with food-grade adhesive as an auxiliary material and is manufactured through a series of fine processes such as high-temperature activation and compression molding. The outer layer of the formed carbon rod is wrapped with a layer of non-woven fabric with a filtering function, which adds a filtration layer and ensures that the carbon core itself will not shed carbon powder. The upper shell 2 is made of food-grade high-strength plastic material injection molding, which has good corrosion resistance and low-temperature resistance and can adapt to complex environmental conditions.

[0026] In this embodiment, two round holes are opened in the middle of the upper part of the lower outer shell 3. The two round holes are assembled and connected with the water channel plate 6. The lower outer shell 3 and the water channel plate 6 are welded by a hot plate. This welding process can melt the surface of the plastic product, and then press the plastic together. After cooling, a strong weld can be achieved. There are four regularly distributed hexagonal concave pillars on the upper part of the water channel plate 6. The four hexagonal concave pillars are connected to the four round pillars on the upper outer shell 2.

[0027] In addition, the lower outer shell 3 is injection molded from food-grade high-strength plastic material, which has good corrosion resistance and low-temperature resistance, and can adapt to complex environmental conditions. The lower outer shell 3 is a double-cylinder style. The space on the left side is used to install the carbon rod assembly, and the space on the right side can also be used to install the carbon rod assembly. Other filter materials can also be installed for secondary filtration of water. The bottom of the inner side of the left and right double cylinders of the lower outer shell 3 is provided with a circular step to facilitate the installation of the carbon rod assembly. A reinforcing rib is set between the double cylinders to ensure the structural strength and stability of the product. The lower part of the outer cylinder is provided with striped texture. This textured design helps to reduce the friction of the outer wall and increase the user's grip.

[0028] Among them, the upper cover 4 and the lower cover 5 of the activated carbon rod play the role of fixing and sealing the activated carbon rod. The upper cover 4 and the lower cover 5 of the activated carbon rod are firmly bonded to the coconut shell activated carbon rod 1 with hot melt adhesive to ensure that the coconut shell activated carbon rod 1 will not be displaced during operation, and at the same time prevent water from flowing directly through without adsorption; the water circuit board 6 is made of food-grade plastic material by injection molding.

[0029] In this embodiment, an upper internal component 9 is provided at the top right side of the inner cavity of the lower outer shell 3, and a lower internal component 10 is provided at the bottom right side of the inner cavity of the lower outer shell 3. A filter cotton 11 is welded below the lower internal component 10. A PP pipe 12 is provided between the upper internal component 9 and the lower internal component 10 on opposite sides. A first sealing ring 13 is provided above the carbon rod cover 4. The first sealing ring 13 is used to ensure stable and effective filtration of the coconut shell activated carbon rod 1 in the left cylinder of the lower outer shell 3. A first water-contacting cavity 15 is formed between the outer side of the coconut shell activated carbon rod 1 and the left end of the inner cavity of the lower outer shell 3. A second water-contacting cavity 16 is opened on the upper surface of the coconut shell activated carbon rod 1. A third water-contacting cavity 17 is formed between the right end of the inner cavity of the lower outer shell 3 and the outer side of the PP pipe 12.

[0030] In this embodiment, the upper internal component 9, the lower internal component 10, the filter cotton 11, and the PP tube 12 are combined to form a secondary filtration structure. The same carbon rod assembly as the left cylinder of the lower outer shell 3 can be used as a substitute, or the filter raw materials can be selected according to the user's needs.

[0031] It should be noted that the filter cotton 11 is made of high-efficiency filter cotton 11, which has good filtration performance and air permeability. The filter cotton 11 is firmly welded to the lower internal component 10 through ultrasonic welding process, which can effectively intercept fine impurities. The PP pipe 12 is made of PP pipe that meets food hygiene standards, which has good corrosion resistance and low temperature resistance, ensuring the safety and stability of water flow.

[0032] Please see Figure 4 In this embodiment, a water inlet 18 is provided on the front side below the water circuit board 6, and a water outlet 19 is provided on the back side below the water circuit board 6. Two sealing ring grooves are opened on the outer surfaces of the water inlet 18 and the water outlet 19, and a second sealing ring 14 is provided in the sealing ring groove.

[0033] Both the inlet 18 and the outlet 19 are cylindrical pedestals.

[0034] Please see Figure 5 In this embodiment, the upper surface of the water channel plate 6 is provided with a first water channel groove 20, a second water channel groove 21 and a third water channel groove 22. The upper surfaces of the first water channel groove 20, the second water channel groove 21 and the third water channel groove 22 are all welded with water channel plate covers 7 by hot plates.

[0035] Understandably, the first water channel 20, the second water channel 21, and the third water channel 22 are used to guide the water flow. The first water channel 20 can guide the water flow from the inlet 18 to the left cylinder of the lower outer shell 3. After the water flow passes through the coconut shell activated carbon rod 1 in the left cylinder of the lower outer shell 3, the water flow flows into the right cylinder from the middle second water channel 21. After passing through the right cylinder of the lower outer shell 3, the water flow flows to the outlet 19 through the third water channel 22.

[0036] In this embodiment, the water channel cover 7 is injection molded from food-grade plastic material. The top is smooth and flat, and the bottom has three protruding ribs. These three ribs correspond to the water channel grooves on the top of the water channel plate 6. The two are tightly connected by hot plate welding to ensure a high-strength fusion between the water channel plate 6 and the water channel cover 7, thus ensuring the product's sealing performance.

[0037] Please see Figure 6 In this embodiment, the handle 8 has an arc-shaped cross-section. The inner side of the handle 8 has two symmetrically distributed pivot parts. The top of the pivot part has an inverted buckle. The inner side of the handle 8 has a crescent-shaped notch corresponding to the crescent-shaped notch on the back of the upper shell 2, which provides convenience for users to pick up and put down the product.

[0038] It should be noted that the handle 8 is made of food-grade high-strength plastic injection molding material. The handle 8 is firmly connected to the upper outer shell 2 by a snap-fit ​​connection and can bear the weight of the filter element.

[0039] The working principle of the above embodiments is as follows:

[0040] During use, water enters through inlet 18, then passes through the first water channel 20 of water circuit plate 6 and enters the first wading cavity 15. The first water channel 20 guides the water flow from inlet 18 to the left cylinder of lower outer shell 3. After being filtered by coconut shell activated carbon rod 1 in the left cylinder of lower outer shell 3, the water flows into the right cylinder of lower outer shell 3 through the second water channel 21 in the middle, and then enters the right cylinder of lower outer shell 3 for secondary filtration. The water flows through the upper internal component 9, PP pipe 12, lower internal component 10 and filter cotton 11 in sequence, which can intercept fine impurities in the water flow. After the secondary filtration is completed, the water flows through the third water channel 22 of water circuit plate 6 to outlet 19. Thus, the complete filtration of water quality is completed.
